Currently using A7.07 pro.
We just spent a week converting our project from A6.314 to A6.4 then to A6.60 then to A7.07.
We have 3 flight sim levels 2 are over terrain.
The problem is we are using:- phent_settype(my, ph_rigid, ph_poly); to set up our jet (mig29 from 100 models and spaceships pack)
In A6.314 collisions with the terrain worked perfectly, with above setup. Any Version above 6.314, as soon as you collide with the terrain, it spits the model out on the underside of the terrain and then the collisions work perfectly from the bottom of the terrain and it is actually a roof! as if the normals are flipped on the terrain!!
OK The workaround of using ph_box solves the problem, but a pointy nosed jet doesn't behave well with a box shaped front end.
- In a nutshell ph_poly seems to be broken.
It behaves completely in reverse and sucks you throught the terrain to the underside of the terrain, and is happy to work on that side correctly.
There has to be a problem here its like the normals are flipped. I've also noticed more suvire collisions in an entirely geometry level as well.
Also our tank (hidden 4 wheel drive) doesn't work as smooth as it used to.
I've tried many things resaving jet and terrain with A7 Trying jet in other levels. Turning off chunked terrain.Flipping the normals on the terrain in MED version 6.24 (A6.314 version)
c_setminmax, makes the box a bit smaller, but still not a jet!
One thing I haven't tried is building a level from scratch with A7.07. As these levels had there original creation in A6.314.

Any help with this would be greatly appreciated.
Jethro.
